dep/animone: make bsd.cc and x11.cc actually work apparently I broke these, and even now the x11 code *still* doesn't want to work correctly (at least on FreeBSD). half of the PID response codes are just 0 or the PID for the X server itself... wtf? maybe dwm just doesn't support the XRes extension, or I'm just stupid. i don't know.
